How do I scan or check for computer viruses?
he best method to check and protect a computer for computer viruses is to use an antivirus program. Many anti-virus programs are available to choose from, but the better-rated brands are Kaspersky, Symantec, Trend Micro, and MSE. You can get just the basic antivirus program or a full antivirus suite, which often include other types of protection beyond just virus protection. You can also try using a free online virus scanner to check for viruses on your computer.
How do they work?
Each antivirus program has a different user interface, but they typically make a Scan option/button readily visible. Clicking the button should begin the process. Although you may have other options before the scan begins, including the option for both a quick and full scan. A quick scan searches the most common areas attacked by viruses and takes less time than the full option. However, a full scan is a better choice to run first as it ensures the program checks all possible places on your computer for viruses.
What happens if the program locates a virus?
After completing a scan the antivirus program displays the results of the scan and any detected viruses. If the program has not already done so, it should ask if you want to proceed with removing the viruses or if they should be quarantined.
Other benefits of an antivirus
Most antivirus programs can also schedule virus scans to run at a selected time each day, week, or month or only scan the computer when it is on but not being used. Also, after installing an antivirus program the program stays open in the background and scans files as they are open, downloaded, or executed.
